India can save up to $1.8 trillion per year with smart urban growth

As India grows, it can choose smart urban growth and save more than US$1 trillion, or get it wrong and face traffic congestion, air pollution, traffic fatalities and poor health, says World Resource Institute’s Aniruddha Dasgupta.

India is at a crossroads, and how its cities develop in the coming several years will shape its future for generations.

While only about one-third of Indians currently live in cities, that number will nearly double, from 420 million to 800 million, by 2050. Whether those people live in safe, productive and clean communities will depend on how India’s leaders guide urban growth.

In fact, the report shows that smart urban growth can save India between $330 billion and $1.8 trillion (₹2-12 lakh crores) per year by mid-century – up to 6 percent of the country’s GDP – and create significant savings for households.

The costs of getting it wrong

India isn’t “sprawled” in the traditional way – Indian cities are among the densest in the world. But the problem is that it is not productivedensity. Instead of multi-level buildings organized into accessible neighborhoods, many Indian cities are filled with short, overcrowded buildings, and lack public transit and pedestrian spaces. So for each square mile of space, there’s a lot less room to live.

One of the key reasons for this is India’s relatively restrictive land regulations, like building height and zoning restrictions, prevent efficient, productive development. Smart urban growth in India therefore will require ensuring compact development without overcrowding and connecting people to places with a variety of transportation options, from bus rapid transit (BRT) to safe cycling.

The cost of getting urbanization wrong is tremendous. Dispersed, low density cities with inadequate mobility options require a lot more money to sustain. When communities are spread out over large distances, infrastructure and services become significantly more expensive to provide, and many people are often forced to spend a lot of money and hours in transit.

The New Climate Economy report notes that providing public infrastructure and services like water, sewerage and electricity is likely to be 10-30 per cent higher in dispersed, automobile-oriented developments than in more compact, connected neighborhoods.

Furthermore, traffic congestion, air pollution, traffic fatalities and poor health are all outcomes of poorly planned cities, creating additional costs both for residents and governments. Owning and operating a car in India costs 12 times as much as using public transport and 30 times more than using a bike.

Delhi, India’s capital, is a stark example of how car-driven growth has led to traffic congestion that costs the economy an average of almost Rs 5 (7¢) per kilometer for cars and Rs 10 (15¢) per kilometer for buses during peak hours as a result of air pollution, wasted fuel and lost time.

Considering the city already has more than 7 million cars — more than 300 cars per 1,000 people — the impact is significant. The recent air pollution crisis has brought global attention to how Delhi’s reliance on polluting vehicles has created a livability crisis that affects all residents.

3 target areas for changing course

But as the new report points out, India has an opportunity to save tremendously by planning cities that are compact, connected and coordinated. By pursuing reforms in three key areas, the country can tap into the potential of urbanization to create social and economic benefits for everyone:

Reforming land regulations can help India better manage its expanding urban footprint. Doing so will help make land use patterns more efficient and effective so that people can live in dense urban communities that work for them.

The kinds of regulations in need of reform include restrictive maximum building heights and parking space requirements, but additional measures to the legal system will be essential, like determining property rights and conducting equitable public land acquisitions.

Expanding sustainable urban infrastructure such as efficient, low-carbon public transport systems like bus rapid transit (BRT) is critical for ensuring that cities adequately meet the needs of their residents.

Strengthening urban local governments, accountability and financing can be key to creating a system of governance that works for sustainable cities. Currently, it’s unclear how responsibilities for managing urban issues are divided between national, state or local governments, and technical capacity for city-led action is low, for example due to a lack of formal training for professionals in urban management.

The national government should undertake reforms to clarify the evolving responsibilities of local governments, strengthen their administrative capacity and expand their fiscal resources.

A sustainable urban future for India

With 400 million new urban residents by 2050 and 75 per cent of national income coming from cities by 2031, there is a lot at stake for India’s urban future. The country’s national and local leaders should recognize the urban opportunity and build on the momentum of newly created central programs like the Smart Cities Mission that aim to get urbanization right.

Doing so will ensure that India’s urban future is one of inclusive and sustainable growth where all people can live in cities and have a high quality of life.
